Reaction of title aziridines with isocyanates in presence of sodium iodide is regiospecific. 2-Aryl N-sulfonylaziridines give the 1-N-arylsulfonyl-3-alkyl/aryl-4-phenyl-2-imidazolidinones exclusively whereas the 2-alkyl substituted aziridines afford only
An improved synthesis of N-arylsulphonyl-2-imidazolidinones through reaction of N-arylsulphonylaziridines with isocyanates catalysed by lithium iodide

N-Arylsulphonylaziridines react with propyl, benzyl and benzoyl isocyanates in the presence of LiI to give improved yield of the corresponding 2-imidazolidinone.
Synthesis of 2-iminothiazolidines through reaction of N-arylsulphonylaziridines with isothiocyanates in the presence of iodide ions

Reaction of 2-substituted N-arylsulphonylaziridines with isothiocyanates using lithium iodide as a catalyst yields iminothiazolidines. Besides the spectral and analytical data, the structure is also confirmed by X-ray crystallographic data. The amount of recovered aziridines decreased by use of DMF and DMSO, instead of acetone, as solvents. The reaction works well also with benzoyl isothiocyanates.
Regio- and stereo-selective reaction of N-arylsulphonylaziridines with trimethylsilyl iodide

Several unknown β-iodophenylethylarylsulfonamides (2a-d) have been prepared in good yields (80-90percent) through regio and stereoselective ring opening of N-arylsulfonylaziridines (1a-e) by trimethylsilyl iodide.
